Nepali Name: बौंडाइ Baudai
1. Loves to hover or perhaps that is how its hunts. Drops straight down when it sights its prey.
2. Has a rather large altitudinal distribution. I have seen one as high as 5,000 m in Langtang (Central Mountains) and as low as 200 m in Dhangadhi (Western terai).
3. Scientists used to say earlier that this bird can detect infra-red emissions of its prey (mostly rats and voles). But now that “fact” is out the door and they say they detect the ultra-violet rays reflected from the scent marks left by voles and rats. I hope they experiment with X-rays soon.
4. Shows marked sexual dimorphism.
Do you love birds and trekking? One of our co-founders of this blog has made a trekking app that shows which bird can be found where along certain trekking regions. The app has redefined what a guidebook or a field book can achieve. It shows information on birds, flowers, animals and butterflies in a context sensitive manner. This means that such flora and fauna is attached only to places where they can be seen and are only shown when they can be seen. Find out more.
